Specification of Letters Patent.

Patented Dec. 19, 1911.

Application filed October 10, 1910. Serial No. 586,161.

To all whom it may concern:

Be it known that I, ALBERT L. SIEGRIST, a citizen of the United States,residing at Akron, in the county of Summit, State of Ohio, have inventedcertain new and useful Improvements in Vehicle-Tires; and I do declarethe followin to be a full, clear, and exact description 0 the invention,such as will enable others skilled in the art to which it appertains tomake and .use the same, reference being had to the accompanyingdrawings, and to the characters of reference marked thereon, which forma part of this specification.

This invention relates to block tires, especially designed for use oncommercial motor vehicles, and consists in the construction andarrangement of parts hereinafter more fully set forth and pointed outparticularly in the claim.

The object of the invention is to provide a tire of the characterdescribed of simple and inexpensive construction, wherein thearrangement is such as to obviate the heating and destructive effect ofthe wave motion incident to continuous-tread tires; to construct theblock-carrying rim of separable sections independently removable; tofacilitate repair by enabling the removal of a worn block only and torender the sections of the rim carrying the blocks cooperative inmaintaining themselves firmly in place and in strengthening the rim ofthe wheel.

The above object is attained by the structure illustrated in theaccompanying drawings, in which Figure 1 is a fragmentary View inelevation showing a portion of a vehicle wheel rovided with a tire inaccordance with my invention. Fig. 2 is a transverse section as on line9r2 of Fig. 1. Fig. 3 is a perspective view of one of the sections ofthe rim with the rubber block removed therefrom.

Referring to the characters of reference, 1 designates the felly of thewheel, which is preferably made of wood, and which is rovided with ametal band 2. The rim 0 the wheel is composed of a plurality of sections3 in the form of metallic yokes which embrace the band 2 and extend ontothe sides of the telly, being secured in Place by the transverse bolts 4which receive on their threaded ends the nuts 5. The sides of said yokesor rim sections are caused to swell outwardly, as shown at 6, to protectthe ends of the bolts 4 from being sheared off by running against thecurb or other similar obstruction.

Formed integral with the rim sections 8 are the hook-shaped clenchermembers 7 between whose inwardly extending terminals the rubber blocks 8which form the resilient tire of the wheel, are placed, said blocksbeing molded or vulcanized in said members of the rim sections topermanently unite the blocks thereto; the completed rim formed by theassembled parts, comprising a plurality of sections or units, eachsection consisting of a yoke adapted to be detachably secured to thetelly and a rubber block forming a portion of the resilient tire.

The yokes 3 are in effect sectors of the rim and are so proportionedthat the projecting shoulders 9 at the terminals of the side portionsthereof, will abut when said sectors are secured in position upon thetelly, as clearly shown in Fig. 1, thereby producing a continuous rimwhich embraces the folly and strengthens the wheel. As an additionalsupport or brace for the detachable sections, the hook members 7 areprovided with flat bearing faces 10 which project into radial alinementwith the abutting shoulders 9 so that the outer faces of said memberswill bear against one another, whereby said rim sections when secured inposition, as shown in Fig. 1, are locked or braced againstcircumferential movement, rendering the outer segmental rim formed bysaid sections rigid throughout the entire circumference of the wheel andenabling them to be securely retained in place by a single bolt 4.

It will be noted that the blocks of rubber 8 are of such shape and areso disposed as to form open spaces 11 between them. This arrangementaffords freedom of movement to each block under compression, producingin effect a softer and more resilient tire, and afi'ording a structurewherein each section of the tire works independently for a short periodof time and remains idle during the further rotation of the wheel untilit again comes into play. By dividing the tire into blocks or sections,as shown, wave motion in the tire is obviated and the kneading actionwhich results in heating in a continuous tire, is largely overcome.

A tire constructed as herein shown, may be readily repaired in case ofinjury by simply removing the section of the rim in which the injuredblock is set and substituting a new section therefor. This operation ofrepairing the tire necessitates the removal of but one bolt and does notrequire the removal of any portion of the tire excepting the sectionactually injured, enabling a repair to be made in a comparatively s orttime.

Having thus fully set forth my invention, what I claim as new and desireto secure by Letters Patent, is

A vehicle wheel tire comprising a rim formed of a plurality of sectlons,each section consisting of a member having inwardly extending sideflanges adapted to embrace the felly and outwardly extending hookportions projecting in a direction opposite to said flanges, means forsecuring each section to the telly and a block of resilient materialpermanently secured between said hook ortions.

In testimony W ereof, I sign this specification in the presence of twoWitnesses.
